What Apple gets and what no one else in the industry does is that using your mobile device for payments will only work if it’s far easier and better than using a credit card. With CurrentC, you’ll have to unlock your phone, launch their app, point your camera at a QR code, and wait. With Apple Pay, you just take out your phone and put your thumb on the Touch ID sensor.
Tim Cook was exactly right on stage last month when he introduced Apple Pay: it’s the only mobile payment solution designed around improving the customer experience. CurrentC is designed around the collection of customer data and the ability to offer coupons and other junk. Here is what a printed receipt from CVS looks like (https://twitter.com/fromedome/status/526027483901333505). It looks like a joke, but that’s for real. And that’s the sort of experience they want to bring to mobile payments.
And the reason they don’t want to allow Apple Pay is because Apple Pay doesn’t give them any personal information about the customer. It’s not about security — Apple Pay is far more secure than any credit/debit card system in the U.S. It’s not about money — Apple’s tiny slice of the transaction comes from the banks, not the merchants. It’s about data.
Apple's great strategic advantages over Google, is that they put their customers (i.e. the people who buy Apple's goods and services) needs over their partners needs to be able to data mine those users.
